The April 18, 1983, United States Embassy bombing was a suicide bombing on the Embassy of the United States in Beirut, Lebanon, that killed 32 Lebanese, 17 Americans, and 14 visitors and passers-by. The victims were mostly embassy and CIA staff members, but also included several US soldiers and one U.S. Marine Security Guard. The attack came in the wake of an intervention in the Lebanese Civil War by the United States and other Western countries. The attacks were claimed by the Islamic Jihad Organization. The United States later believed they were perpetrated by Hezbollah, but Hezbollah denied responsibility.
